APPARATUS FOR CHARGING AND DISCHARGIN G GAS-RETORTS.

To all 'whom t may concern:

Be it known that we, HENRY A. CARPEN- TER, ROBERT L. HIBBARD and ARTHUR l/V. VARNER, citizens of the United States, residing at Sewickley, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Apparatus for Charging and Discharging Gas-Retorts, of which the following is a specification.

Our invention relates to apparatus for charging retorts, etc., and more particularly to apparatus for charging and discharging horizontally disposed gas retorts, although it may be employed for example in charging ore into furnaces.

An object of the present invention is to provideA new and improved means for preventing the escape, into the gas house, furnace house, or other building, in which the apparatus is located, of the material designed to be charged into the retorts or furnace.

In the drawings we have shown our invention embodied in a charging and discharging apparatus adapted to travel along a track arranged parallel with a series of gas retort benches, with said apparatus including a hopper designed to carry a supply of coal, a charger and discharger adapted to receive a charge of coal from the hopper and to convey said charge into a retort, mechanisni for raising and lowering the hopper and charger and discharger, means for discharging the coal into the retort, and operable mechanism for moving the apparatus along the track aforesaid.

In the accompanying drawings, which illustrate an application of our invention:

Figure 1 is a rear elevational view` ofv the means for preventing the escape of the material or coal dust, shown in connection with a section of a coal hopper, a telescopic chute leading from the hopper to the charging and discharging' member, a motor, and a portion of the gearing employed; Fig. 2 is a part elevational view and a part vertical sectional view through a portion of the hopper, telescopic chute, andthe means for preventing' the escape of dust, etc., at the discharge end of the chute; and Fig. 3 is a side elevational view particularly showing the mechanism for operating the means for Specification of Letters Patent.

Application filed February 15, 1913.

Patented net. s, 191e. Serial No. 748,644.

of a hopper liXedly secured to the upper end of the frame, said hopper being provided with gates 3 mounted on and operable through shafts 4.

Interposed between the lower end of the l hopper 2v and a charger and discharger y5, we provide a dust-tight telescopic chute 6. The said charger and discharger 5, together with the telescopic chute 6, are indirectly supported from beams or girders 7, which girders or beams are connected with vertically extending screws 8 designed to raise and lower the girders 7 vtogether with the charger and discharger 5 andthe chute 6. As the charger and discharger 5 and the mechanism for raising 'and lowering the same form no part of the present invention, the same being fully shown and described in a pending application, Serial Number 530,383 filed November 29, 1909, we deem it unnecessary in this application to more fully describe said parts and mechanism.

The telescopic chute extending downwardly from thel hopper a short distance above the charger and discharger 5, as illustrated, comprises a dust proof structure including a liXed section 9 secured to the lower end of the hopper, and a series of telescopic sections 10. Secured to the lower end of the section 9, we provide a band or strip 11, and each of the telescopic sections 10 is provided with a similar band or strip 12, said sections l0, in addition to the bands 12, are each provided at its upper end with an inwardly projecting flanged portion 13 and an outwardly projecting flanged portion 14. As the telescopic series of the chute are lowered, the inwardly projecting flanged portion of each adjacent section will engage the band or strip located at the lower end of the preceding adjacent section, vand said flanged portions 13 and 14 of the respective sections coact to prevent the 4escape of material or dust at the joints of the several sections.

The outermost section 15 of the telescopic chute has its lower end entered in a metallic seat or casing 16, said casing being provided with anged portions 17 and connectel with Cir the respective girders 7 by means of brackets 18.

The means for preventing the escape of dust, etc., between the discharge end of the chute and the charger and discharger, as

illustrated, comprise two movable side members or wings 19, a front member or' wing 20, and a rear member or wing 21. These closure means comprising the said front, rear and side wings are adapted to be closed down over the upper open portion of the charger and discharger 5 as shown in full lines in Fig. 2, and adapted to be raised after a charge of coal has been introduced to the charger and discharger into the position shown by dotted lines in the same figure, the wings being shown in raised positio-n in Fig. 1.

The upper edges ofthe respective side wings 19, front wing 20, and rear wing 21, are respectively provided with reinforcing strips 22, 23 and 24 designed to beconnected with the side, front and rear portions of the casingy 16 by hinges 25, 26, and 27. The front wing or member 20 is formed with side -flanges 23 adapted to overlap the front ends of the side wings or members 19, and in addition to the said flanges 28, it is provided with a depending portion 29 adapted to enter the interior o-f the charger 5, as particularly shown by Fig. 3. The rear wing 21 is provided with a horizontally projecting portion 30 designed to overlap a cover-plate 31, and with side flanges 32, which latter, when the closure members are closed, overlap the rear ends of the side members 19.

The means illustrated for the purpose of operating the closure means include an elec tric motor 34 supported by projecting channels 35, the latter being supported by the girders 7. Mounted on the motor shaft 36 is a pinion 37, which pinion meshes with a spur gear 38 carried on an end of a worm shaft 39. Worm shaft 39 is adapted to drive a worm wheel, not shown, located Within the gear casing, and the last mentioned worm wheel drives an eccentric 40wliich latter is connected with; arm 41 keyedv to a: shaft 42. Shaft 42 has mounted thereon a bevel-gear 43 designed to mesh with a pinion 44 carried on a shaft 45 extending along one side of the chute.

Located on the opposite side ofthe telescopic chute from the shaft 45, we provide a shaft 46. As shaft 45 is revolved by the gear mechanism above described, motion th-erefrom is transmitted to shaft 46 through gear sectors 47 and 43, respectively keyed to the shafts 45 and 46.

The side wings 19 are connected with the respective shafts 45 and 46 by means oflink connections comprising members 49 keyed to the respective shafts 45 and 46, intermediate members 50, and lower members 51. The last mentioned members 51. are respectively secured to the wings 19 by means of bolts 52 entered in clips 53, said clips being riveted to the wines.

The forward wing 20 is connected with the respective shafts 45 and 46 by means of a link connection comprising a member 54 and a jointed rod 55 said rod 55 being provided with a turnbuckle 56 and having its upper and lower ends each respectively provided with a ball 57 and 53 formed integral with the said ends thereof. The ball 57 lits in a socket 59 partially formed in the arm 54 and partially formed by a cap 60 secured to saidl arm 54 by bolts 61. rThe lower end of the jointed rod 55 or the ball 53 thereof is fitted into a socket formed partially in the clip 62 and a cap 63 secured thereto, the clip 62 being riveted to the front face of the fro-nt wing.

The construction just described for con necting the front wing with the shafts 45 and 46 is similar to the construction employed for connecting the rear wing 21 to the respective shafts 45 and In the use of charging and discharging apparatus, particularly where the apparatus is employed in gas houses in the manufacture of gas, it is very important that the escape of coal dust be prevented, and by the construction illustrated, we provide means 9 for effecting this end, the dust-tight telescopic chute preventing the dust escaping into the building during the passage of the coal from the hopper through the chute and the closure means located at the discharge end of the chute and between said ends and the charger and discharger, preventing the escape at this point.

In the construction illustrated, it will, of course, be understood that during the passage of coal from the hopper to the charger, the closure means comprising the several wing members are closed down over the charger as shown in full lines in F ig. 2. After the charger 5 has been lilled with the coal to be conv-eyed into the retort, the wings are raised by means of the motor and the operating mechanism interposed between the said wings and the motor, thus enabling the charger and discharger 5 to be moved horizontally into a retort.

T he closure means interposed between the lower end of the telescopic chute and the charger 5 shapes the charge in said charger as indicated by 64 (see Fig. 1), and in this figure, 65 indicates the retort into which the charge is delivered. In practice, the charge 64 while in the charger and prior to its introduction to a retort, is carried into contact with means for compressing or shaping the charge to prevent it from coming into co tact with the mouth-piece of the retort. These means form no part of the present invention, but are fully shown and described ina separate. application for patent, Serial Number 748,643, February 15, 1913.
